That locks in your vehicle so every part we show fits. Genuine GM parts at up to 40% off dealer prices.
Getting parts right on a heavy duty pickup starts with knowing which generation you are working on. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.
2020 is a carryover year for this vehicle. That makes sourcing simpler in the mechanical systems and no simpler at all in trim and body. GM made running changes mid-year on several heavy duty components, so the correct part can depend on build date rather than model year alone.
The parts we ship most for the 2020 Chevrolet Silverado 2500 HD are EGR coolers, front hub assemblies, leaf springs and shackles, steering linkage and drag links and brake rotors and calipers. Everything on this page is a factory GM part, built to the original specification and carrying the original part number. On a heavy duty pickup these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.
Where geography matters is landed cost. A heavy part quoted a few dollars cheaper by an East Coast seller often costs more delivered to the middle of the country than the same part shipped out of Dallas. Compare the total, not the sticker.
If you are not certain which version you have, give us the VIN and we will confirm fitment before you check out. In stock orders placed by 2pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. Parts for the 2019 Silverado 2500 HD and the 2021 Silverado 2500 HD are listed separately, because the differences between adjacent years are real.
We specialize in GM vehicles that are 10 to 15 years old, and we often carry new-in-box parts for older models too. Discontinued parts are a normal part of the OEM business. When GM stops making a part and our stock is gone, that is the end of the line for that OEM part. We thank you in advance for understanding. The GM Parts Club advantage: our massive buying power lets us stock deep on the parts GM owners need, in our huge warehouse in Dallas, Texas.
